eclipse - EclipseFP が機能しない

Question

Mac OS Yosemite 10.10.5 の Eclipse バージョン: Mars Release (4.5.0) に EclipseFP をインストールしようとしています。

Haskell パースペクティブが表示されている間、Haskell 言語に特別な機能はありません (構文の強調表示、フーグル検索など...)

これが私のEclipse設定です：

そして、問題は、必要なすべてのパッケージをコンパイルできなかったことです (ただし、これが根本的な原因であることを確認してください)。

たとえば、Haskell ヘルパー実行可能ファイルで「Install from Hackage」ボタンを押すと、コンパイルしようとしますが、次の理由で失敗しますghc-pkg-lib-0.3。
